DAYUAN Motorcycle Flywheel Puller Set — 10-Piece Multi-Thread Kit with Black Oxide Steel Pullers and Molded Case

DAYUAN Motorcycle Flywheel Puller Set is a 10-piece, multi-thread toolkit designed to remove flywheels and stators from a wide range of small engines on motorcycles, scooters, ATVs and dirt bikes.

This compact kit groups five single-ended and five double-ended pullers in a molded storage case so you can match the correct thread and pitch for common European, Japanese and Chinese small engines. Every puller is machined from steel and finished with a black oxide coat to resist corrosion in the workshop. The set covers many standard sizes and thread directions, giving a one-stop solution for routine service, roadside repairs and hobby bike projects.

Which engine models and tasks will this puller set work for?

The DAYUAN set targets a broad mix of small-displacement engines found on commuter motorcycles, scooters, ATVs and off-road bikes. It is intended for removing tapered flywheels, stators and similar press-fit components that require a threaded pulling tool.

• Fits common flywheel thread sizes used by Japanese and Chinese manufacturers.
• Useful for stator and rotor removal during ignition or charging system work.
• Sized for many scooters, dirt bikes and small ATVs — check your flywheel thread before use.

How do I choose the correct puller size and thread direction?

Select the puller that matches the diameter and thread pitch on your flywheel hub. The set includes both single-ended and double-ended pieces to address different thread patterns; note that only the M27x1.0 piece is left-hand — the rest are right-hand threads.

• Measure flywheel thread diameter and pitch or consult your service manual.
• Use the appropriate single- or double-ended adapter to secure positive engagement.
• If unsure, test-fit gently to confirm thread compatibility before applying force.

What construction and storage features help durability and workshop use?

Each puller is manufactured from heat-treated steel with a black oxide finish to improve wear resistance and reduce surface rust. The kit ships in a blow-molded case that keeps the tools organized and protected between jobs.

• Black oxide coating extends lifespan and reduces corrosion on exposed threads.
• Solid steel construction withstands the torque needed for stubborn flywheels.
• Molded case secures each piece to prevent loss and speeds tool selection.

What safety and best-practice tips should I follow when using a flywheel puller?

Always secure the engine or wheel to prevent rotation and wear appropriate eye protection when applying puller force. Work gradually and evenly; using excessive impact or angle can damage the flywheel, crankshaft threads or the puller itself.

• Lock the engine or gearbox to stop unintended movement during pulling.
• Apply steady, controlled pressure—avoid hammer strikes on the tool threads.
• Inspect threads for damage and replace worn components before reuse.

Who is this for: The DAYUAN 10-piece flywheel puller set suits home mechanics, motorcycle shop technicians, ATV and dirt-bike riders who perform routine maintenance or repairs, and hobbyists restoring small engines. It’s especially helpful if you work on multiple bike brands and need a compact solution that covers a wide range of thread sizes and pitches. Always confirm your engine’s thread specifications before use to ensure compatibility and safe removal.
